Inexpensive wings/DIY setups
I am in love with the APR wing, but can't justify the $650 right now, how many track guys have successfully used Ebay or other type wings? I know there have been a few that have gone this route, but can't find much on it right now.
I am thinking about getting a wing that looks halfway decent and making my own legs for it, but I am worried it will not be adjustable to be secured correctly.

i used basically an ebay wing and made my own legs for it out of aluminum.
i made 4-5 holes on the legs for adj. when combined with the 3-4 holes on the wing attachments, it makes for a lot of adj. angles. i then used the string method (yarn) with my gopro cam to see which setting yielded the most down force. you can even see what happens when you go too steep. especially with the 3d type wings, if you go too steep, the airflow stalls and basically at that point it becomes nothing but drag. main diff. between my wing and the apr is the "chord length?" not sure if thats what its called. basically the length from the leading edge to the trailing edge. i think the longer that is, the more surface area, the more downforce possible. this is all stuff i think i remember reading somewhere. where's emilio?

Here go one that I did myself. It's not all fancy like the APR one, but buy doing it myself, I paid a fraction of the cost of an APR.

I just ordered: 61" Ebay Wing and I will see how sturdy the legs are for it, but more than likely will be making my own setup to be at the edges of the trunk. I will post up how it goes.

my carbon wing is actually an arospeed wing. we had those wings like you bought at our shop years ago. arospeed has been out of buisness for 3-4 years now. i actually have a wing that you might like a little more. it has a gurney flap on it, and the legs are pretty stout. i can send you a pic if you'd like. we could sell it for $69.99. normally sell for $149.00.

I ordered an apr duel element aluminum wing (for a friend) and a cheap ebay dual element aluminum wing (for me). The wing elements were very similar. The larger element on the ebay wing (7.5") was the same as the less cambered apr element. The supports were much stronger on the apr wing. I have added some stregth to the ebay supports, but have yet to test it. I also plan to add a gurney flap. The apr was about $400 and the ebay one was $100 shipped.
This one icludes a 7.5" low cambered element and a 5.5" high camber element.

There's an interesting thread on NASIOC in the Motorsports forum. Phil from Element Tuning modified their wing (APR, IIRC). The wing came off prior to a series of esses at VIR. He went off the track at 148 mph.
Just be careful what you buy, how you install it, and using it per manufacturers instructions. In other words, eBay (i.e., little or no documentation regarding usage and setup), beware.

Everything will be redone on my wing to make it a rigid as possible. I just went to a local metal suplier and found some 1/4" aluminum that I will be using for the legs and will weld the scrap off of that to it for a base. At the wing, the adjuster will be welded directly to the wing as to minimize failure points. Basically, the only part that will be a possible failure point will be the spot directly below the wing where I adjust the angle.
